A recent study suggests that at certain population densities, hen harriers can co-exist with profitable grouse shooting.
Scientists have said this could be achieved using a simple approach, where when harriers breed at levels that have a significant economic impact on grouse shoots, the excess chicks would be removed from the grouse moors, reared in captivity and then released into the wild elsewhere.
The next step is for grouse managers and conservationists to use the results of the model to agree on an acceptable number of harriers and then test the idea in a field trial, the research published in the British Ecological Society's Journal of Applied Ecology suggests.
